Some specimens, from Queensland (Coen River and Cook- 

 town) and North-western Australia (King Sound), are con- 

 siderably larger (up to 15 mm.), and have the tips of the 

 tibiae, labrum (wholly or in part) and palpi blackish, with 

 the knees infuscated or not. 



Metriorrhynchus cancellatus, Lea. 

 A female of this species, f rom Gosford (New South Wales), 

 has the antennae much less strongly serrated than in the male, 

 and the third joint of antennae no longer than the fourth. 



Metriorrhynchus diminutivus, Lea. 



Two females, from Cairns, probably belong to this species, 

 they differ from the description in having the dark parts black 

 instead of blackish-brown, the scutellum no paler than the 

 elytra, and the antennae, except the minute second joint, 

 entirely dark. 



Metriorrhynchus ramosus, Lea. 



Two males, from Mount Tambourine, probably belong to 

 this species, but differ from the type in having the antenna! 

 rami shorter, and rather less of the elytra black. 



Metriorrhynchus parvoniger, n. sp. 

 o* . Sooty-black. 



Head irregularly concave between eyes, muzzle very short. 

 Antennae rather long and feebly serrated, third joint the 

 length of fifth and slightly wider, but at apex no narrower 

 than fourth, slightly longer than the apical width, the others 

 all distinctly longer than wide, after the sixth decreasing in 

 width, and after the eighth in length also, but eleventh 

 slightly longer than tenth. Prothorax small, seven-areolate, 

 apical costae sharply defined and rather long, front angles 

 almost rectangular, hind ones acutely produced, sides angu- 

 larly diminishing to middle. Scutdliun obtusely bilobed at 

 apex. Elytra with single rows of large, transversely-oblong 

 punctures, close to base a few doubled. Length ( d , 9)> 

 5*5-6 mm. 



9 • Differs in having antennae shorter, thinner, and even 

 more feebly serrated, and in the abdomen. 



Hab. — Queensland: Cairns district (E. Allen and A. M. 

 Lea). Type, I. 11810. 



On each elytron almost throughout there are but five 

 rows of punctures, about the tips they are less angular than 

 elsewhere, and close to the base a few of the punctures in 

 the second and third rows are doubled. The female, taken 

 in cop. with the type, has the sides of the prothorax obscurely
